When Should You Go With 48V Batteries?

Choosing between a 12V, 24V, or 48V battery system is not as simple as saying one is always better than the others. It really comes down to how much power you need, how many batteries your system will use, what size inverter you want to run, and how much space you have available.

For smaller setups, a 12V system can still be a great fit. It works well for lighter power needs and smaller battery banks. As you start adding more batteries, though, the system can become more complicated, and keeping everything balanced over time may become more difficult. That is often when it makes sense to start looking at 24V.

A 48V system is usually a better fit for larger builds with bigger power demands. If you want to run air conditioning, a larger inverter, or several appliances without constantly turning one thing off to use another, 48V may be worth considering.

In this tech tip, Todd also takes a look at our brand-new Goliath 48V 300Ah lithium battery. With 14,640 watt-hours of energy in one battery, The Goliath gives you a lot of capacity without needing a large bank of separate batteries.

Of course, power is only part of the decision. You also have to make sure the battery fits your space. In a cargo trailer, placing The Goliath along a wall may be easy. In an RV with limited storage, a 12V or 24V setup may still be the better choice.

There is no one-size-fits-all answer. The best system is the one designed around your rig, your travel style, and how you actually plan to use your power.
